Introduction With the popularity of nonvolatile random access memories (NvRAMs), more and more attention has been paid to the study of ferroelectric materials[1, 2].
Recently, much intention has been focused on the sodium bismuth titanate (NBT) systems as one of the key lead-free piezoelectric materials.

For fine-grained, polycrystalline materials, the most suitable technique to detect microstrains is diffraction of synchrotron hard X-rays that can operate with high spatial resolution and are intense enough to achieve bulk penetration.
The microscope in ESRF, ID-11 Materials Science Beam line was used in this experiment.

Microstructure Evolution of PtTi0.5Zr0.2/Ti laminated Composites Synthesized by Hot Pressing and Rolling Ye Fana, Xiaoge Zhangb, Qiong Zhaoc, Guoyi Qind*, Siyong Xue and Jinxin Guof The Key Laboratory of Micro-nano Materials and Tehnology, Department of Materials Science and Engineering, Yunnan University, Kunming 650091, China.
Therefore, PtTi0.5Zr0.2/Ti laminated composite materials have a great significance for the development of precious metal materials with lower-cost, higher performance and better mechanical properties.
Smaller and more interface layer spacing effect make the micro laminated materials that are better than the corresponding monomers materials on the performance [2, 3].

It is therefore necessary to define the basic physical processes in materials during heating generated by laser beam.
The operation of the laser beam for a certain time leads to the conversion of absorbed optical energy to thermal energy in the material, which heats a volume of the material – phase transition may occur depending on the temperature in that part of the volume.
In the centre of material it is not enough time for growth of α-phase dendrites in all directions.

Research On The Risk Entropy Model Of Water Supply Systems Based On Entropy Theory LU Ren-qiang Department of Civil Engineering and Construction Management, Hunan University of Science and Engineering, Yongzhou 425100, China lrq150@163.com Keywords: entropy theory; water supply systems; risk entropy; model Abstract: According to the uncertainty characteristics of water supply systems when it suffered by the threats, the entropy function was introduced into water supply systems for the risk assessment studies, and the risk entropy model of water supply systems was proposed.
It is also the essential material basis for economic development, and has an extremely important position to protect the people's normal life.
Risk assessment theory of water supply systems The term of risk has been widely used in environmental, ecological, disaster science and other fields.
